A little off topic here but does any one know were I could order springs online that would ship to Canada. Mcmaster wont ship to Canada unless your a long time customer.
In terms of putting the ribs vertically or horizontally it really depends on the angle of the force, if the x-axis of the force is greater the the y-axis then horizontal ribs would be best, y-axis>x-axis then vertical ribs would be best. (Hopefully this makes sense with the diagram.)
If you want to use a more elaborate rib system I would go with Just Some Bob's diagram.
Hey guys, any one know were I could order springs (online) in Canada. Tried Mcmaster but they said they only ship to Canadian clients who are "well known"...
